If you only install slip on muffs, no ECM flash required. If you install a free flow intake and free flow muffs you need an ECM flash. If you are getting cams, get a flash. You could also install a tuner for all of the above instead of an ECM flash. That would give you the freedom to tune the fuel/air mixture for any combination of exhaust, intake or cams.
